Application February 18, 1931, Serial No. 516,597 Renewed October 10, 1932 15 Claims.

This invention relates to fire walls for furnaces, and more particularly to walls of this kind that are-composed of blocks which are interlocking and which are removable.

Generally stated, the object of the invention is toprovide a novel and improved construction and arrangement whereby certain of the blocks are larger than others, and adapted to engage metal anchoring devices fixed in the outside wall of the furnace, while other blocks are of different shape and size and are adapted to interlockingly engage the said larger blocks, whereby to provide a fire wall of fireproof blocks that will stand a high temperature, and which can be easily assembled in place, or easily separated and removed when occasion requires. 7

It is also an object to provide certain details and features of construction and combinations tending to increase the general eiiiciency and desirability of a furnace fire wall of this particular character.

To these and other useful ends, the invention consists in matters hereinafter set forth and claimed and shown in the accompanying drawings, in which Fig. 1 is a horizontal section on line 11 in Fig. 2, showing a wall embodying the principles of the invention;

Fig. 2 is a vertical section on line 2-2 in Fig. 1 of the drawings;

Fig. 3 is a perspective of three difierent shapes or sizes of blocks employed in constructing the said wall;

Fig. 1 is a perspective of a wall embodying the principles of the invention, showing some of the blocks in section, and showing the outside wall construction to which the blocks are anchored, and showing certain portions omitted or broken away for convenience of illustration.

As thus illustrated, the invention comprises the relatively large blocks 1, which are provided at their upper and lower ends with sockets 2 for engagement with the metal anchoring devices 3, 45 shown in the drawings. The sides of this block are provided with projections 4 at one side, and

with projections 5 at the other side, the projections at one side being opposite the spaces between the projections at the other side. It will be seen that said projections 4 and 5 have vertically disposed grooves 6, as shown, and that the spaces between said projections have vertical ribs '7, as shown. The devices 3 are preferably fixed on horizontal U-bars 8, supported by vertical I- beams 9 immediately outside of the insulating wall 10 of the wall structure.

The next smaller size block 11 is smooth on its side 12, but has its other side 13 provided with a vertical rib 14 and with the vertical groove 15, as shown. The ribs 14 of the blocks 11 engage the ribs '7 of the blocks 1, in the manner shown, when the blocks are assembled in place.

The smallest size block 16 has one side provided with a vertical groove 17 and has the other side provided with a vertical rib 18. The grooves 1'7 of the blocks 16 engage the ribs 14 of the blocks 11, while the ribs 18 of the blocks 16 engage the grooves 15 of the blocks 11, when the blocks are assembled together. This is shown more clearly in Fig. l of the drawings, where it will be seen that the blocks 11 are turned back to back, so to speak, and. arranged in pairs, with the rib 14 of one block opposite the groove 15 of the other block, and with the groove 15 of the other block opposite the rib 14 of the one block. In this way, the blocks 11 are anchored to the blocks 1, and the 75 blocks 16 are anchored to the blocks 11, in the manner shown.

The building-up process is illustrated in Fig. 4 of the drawings.

It will be seen that the blocks 1 are irregular in formation, while the blocks 11 are of regular and oblong rectangular formation, while the blocks 16 are substantially cubical in form. The outer surfaces of the blocks 11 and 16 are flush, as shown, thereby forming the inner surface of the furnace wall.

, Thus, as shown, the blocks 16 are substantially the same in size as the sections 4 of the blocks 1, assuming that these sections are separated horizontally, or by horizontal planes. The dif- 9O ferent blocks are shown interlocked, but they may be fastened or joined together in any suitable or desired manner. Also, while the blocks 1 are shown as having the sections 4 and 5 in staggered relation, it is obvious that these blocks may be suitably formed to cooperate with the other blocks, in any suitable or desired manner.

What I claim as my invention is:

1. In a furnace fire wall construction, the combination of upright blocks having spaced projections on each side thereof, the projections on one side being opposite the spaces on the other side, an outer frame, devices for anchoring said blocks to said frame, said blocks being arranged one on top of the other in spaced vertical columns, blocks inserted in said spaces between the columns, projecting outwardly a distance beyond the columns, and other blocks interposed between the projecting portions of said second mentioned blocks, and second and third mentioned blocks having flush outer surfaces forming the surface of the wall.

2. A structure as specified in claim 1, said anchoring devices comprising metal projections extending between the upper and lower ends of the first mentioned blocks, these blocks having their upper and lower ends formed with sockets to engage said metal projections.

3. A structure as specified in claim 1, all of said blocks having vertically disposed ribs and grooves for interlocking the blocks together, whereby the second mentioned blocks are interlocked with the first mentioned blocks, and whereby the third mentioned blocks are interlocked with the second mentioned blocks.

4. A structure as specified in claim 1, said second mentioned blocks being disposed in pairs back to back, each pair between a recess of one of the first mentioned blocks, and a projection of another of the first mentioned blocks, and said third mentioned blocks being each disposed between two of said pairs of second mentioned blocks.

5. A furnace fire wall comprising a first set v of blocks in one vertical plane, a second set of blocks removably interlocked with the first mentioned blocks, and a third set of blocks disposed in another vertical plane and removably interlocked with the second set of blocks, the blocks of the second set extending into said first mentioned plane and also into said second mentioned plane.

V 6. A structure as specified in claim 5, the second set of blocks and the third set of blocks having flush outer surfaces forming the inner surface of the furnace wall.

7. A structure as specified in claim 5, in combination with an outer frame, and means for anchoring the first set of blocks to said frame, and a wall between said frame and all of said blocks.

8. A structure as specified in claim 5, the first set of blocks being irregular in formation, the second set of blocks being of regular and oblong rectangular formation, the third set of blocks being cubical in formation.

9. In a furnace fire wall construction, the combination of blocks arranged vertically, end on end, to form vertical tiers of blocks, with the tiers spaced apart, other blocks arranged between and projecting from the spaces between said tiers, and a third set of blocks disposed between the projecting end portions of said other mentioned blocks, the outer ends of said other blocks being flush with the outer surface of said first mentioned blocks, and the inner ends of said other blocks being flush with the inner surface of said last mentioned blocks.

10. A structure as specified in claim 9, said first mentioned blocks having lateral projections, with spaces between said projections, and said second mentioned blocks being all of the same size and shape, and said third mentioned blocks being all of the same size and shape.

11. A structure as specified in claim 9, said second mentioned blocks being disposed in pairs forming columns, with the pairs in staggered relation or laterally displaced in each column.

12. A structure as specified in claim 9, said first mentioned blocks having lateral projections with spaces between said projections, the projections having vertical grooves, and the spaces having vertical ribs, and said second mentioned blocks having both ribs and grooves, and the third mentioned blocks having both ribs and grooves, whereby the blocks all interlock together.

13. In a fire wall construction, a plurality of solid blocks disposed vertically in said wall, in spaced vertical rows, with the vertical dimensions the same in each vertical row, each block being formed in one piece and having a plurality of cavities one above another at one side, and a plurality of projections one above another opposite said cavities at the other side, and other blocks spacing said rows apart and engaging in said cavities, and engaging the ends of said projections.

14. In a, fire wall construction, a plurality of solid blocks disposed horizontally in said wall, in spaced vertical double rows, with the vertical dimensions the same in each vertical row, each block being provided with a vertical rib near one end and with a vertical groove near its other end, said blocks being disposed in pairs back to back with their ribbed and grooved sides at opposite sides thereof, in combination with other blocks spacing said rows apart and engaging said ribs and grooves.

15. In a fire wall construction, a plurality of solid blocks disposed in spaced vertical rows and each having a vertical rib on one side and a vertical groove on the other side thereof, with the vertical dimensions the same in each vertical row, said blocks being disposed in pairs, one outside of the other, so that one block of each pair forms a portion of the outer side of the wall, while the other block of each pair forms a part 125 of the inner side of the wall, in combination with other blocks spacing said rows apart and engaging said ribs and grooves, serving to hold the heads of each pair against separation in the wall.
